Perfectly reasonable:

I'm a huge PG fan, so I start everything with it, but SQLite is sane, and it generally has a happy upgrade path to PG If you need it.

It's the other way around for me: as 99% of the stuff I develop is .NET (and I use EF Core for database stuff), I can get away with SQLite for local development, prototyping (and even staging), and then just "flip a switch" for it to run on production PostgreSQL.

Both are amazing technologies.
